javascript - 基于两个属性从 JavaScript 中的对象数组中获取唯一数组

Question

我需要从数组对象中获取唯一值。例如我有以下数据，

   var empDetails =[
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},{"name":"dinesh","age":"24","companyName":"ABC","designation":"TestEngr"},
{"name":"Ramesh","age":"24","companyName":"ABC","designation":"developer"}];

我想从这个对象中获取唯一的数组详细信息。 输出应如下所示:

uniqueDet = [
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},
 {"name":"dinesh","age":"24","companyName":"ABC","designation":"TestEngr"},
    {"name":"Ramesh","age":"24","companyName":"ABC","designation":"developer"}]

根据公司名称和名称，我想获得独特的详细信息。 您能给我解决方案来解决这个问题吗？ 提前致谢。

Answer 1

var uniqueDet = empDetails.filter(function(x, i) {
    return empDetails.map(function(e) { 
        return JSON.stringify(e)
     }).indexOf(JSON.stringify(x)) == i;
});
